Valuation method in detail
How the estimate is made
The estimate for 17 Caernarvon Way is modelled from its 89 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in CF3 1RW. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 1 sale is recorded for 17 Caernarvon Way. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.

Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 17 Caernarvon Way. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF3 1RW.
Council tax band
17 Caernarvon Way is in council tax band C. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
